NITED STATES EDXVARD T. YOUNG, OF DETROIT, MICHIGAN, ASSIGNOR OF ONE-HALF TO WILLIAM SCOTT, OF SAME PLACE.

REVERSING MECHANISM FOR ELEVATORS.

SPECIFICATION forming part of Letters Patent NO. 4=28,196, dated May 20, 1890.

Application filed January 14, 1889. Serial No. 296,317. (No model.)

To all whom, it may concern.-

Be it known that I, EDWARD T. YOUNG, a citizen of the United States, residing at Detroit, county of \Vayne, State of Michigan, have invented a certain new and useful Improvement in Reversing Mechanism for Elevators; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a reversing mechanism for elevators; and itconsists in the construction and combination of devices hereinafter described and claimed.

In the drawings, Figure 1 is a side View of the elevator-shafts with the car thereon and the operatin'gconnections. Fig. 2 is a perspective view of the beltshifting device. Fig. 3 shows the driving-gearing for revolving the shafts and the reversing mechanism. Fig. 4 is a side elevation of the belt-shifting device.

In the above drawings, A represents the car of the elevator.

B are what may be termed sleeves, attached to the sides of the cartwo at the top and two at the bottom. On the inner surfaces of these sleeves are journaled small wheels or rollers.

O O are two vertical shafts, between which the car A is adapted to travel. These shafts are provided with spiral tracks, and the sleeves B embracing the shafts the wheels or rollers will rest on said track, and thus the sleeves will support the car.

D D are gears rigidly engaged to the base of the shafts and adapted to revolve horizontally, being supported by the rollers d. Meshing with these gears D D is the horizontal gear E. This gear has on its upper surface the beveled pinion e, which meshes with the pinion E, the latter being keyed to the shaft F.

G is a belt-pulley rigidly keyed to the shaft F. G is a loose pulley on said shaft, and G2 is another loose pulley on the said shaft. The hub g of the pulley G is provided with revolve the shaft F, and this shaft being geared to the vertical shaft 0 C the latter will be revolved, and thus carry the car upward. By shifting the belt to the loose pulley G the car will remain stationary, and by shifting the belt to the pulley G2 the shafts will be revolved in the opposite direction and the car lowered.

Fig. 2 represents the belt-shifting device. This is accomplished by extending the rod 7c from the base of the elevator-way up through the car to the top of the way. The lower end of the rod is attached to the bell-crank K, and the rod It is also attached thereto. The other end of the rod is attached to the sliding piece 7a, which Works in the guides 76*. Mounted vertically on the piece 70 are the arms k These arms are adapted to extend up and embrace the belt.

The operation of the belt-shifting device is obvious. By raising the rod is the belt is shifted to the pulley G. By pushing the rod down the belt is shifted to the pulley G K are stops adapted to limit the play of the piece it.

What I claim is A reversing mechanism for elevators, con sisting of the gears D D, wheels rigidly attached to the base of the shafts, gear-wheels E E, meshing therewith and adapted to actuate the same, and the pulleys G G and gearing 11 H H H H all adapted and arranged to rotate the wheel E in different directions at will without reversing the engine, substan tially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

EDWARD T. YOUNG.
